Filed: 1980-07-03
Abstract: PURPOSE:To remove retention in a screw head, and to prevent curing due to thermal deterioration by supporting a nose section of the screw of an extruding machine by the die plate. CONSTITUTION:A resin raw material is melted by means of a double spindle extruding machine 1, and a mixture is homogenized and supplied to the single spindle extruding machine 2. The single spindle extruding machine 2 transports forward the resin raw material, in which the melted mixture is homogenized, through the revolution of the screw 3, and the raw material is discharged in a stringy shape  from the die plate 5 with nozzles 4 for discharging the raw material mounted to the  nose section, and cut in a uniform granular shape by means of a cutter 6. A hole 10  for cooling is formed to an axis of the screw 3, and the heat of the resin raw material from the inside of the screw is removed. Accordingly, the nose section does not  swing because the screw 3 does not turn as it is left as it is open-sided as seen in  conventional devices, heat from the inside is taken away and the raw material does  not stay at the nose section of the screw head.

Title: Variable power type copying machine
Inventor: WATABE SUSUMU
IPC: G03B27/50
Filed: 1983-05-24
Abstract: PURPOSE:To correct the length of an optical path accurately and simplify the constitution of a copying machine by moving the 2nd mirror by a means which couples a movable support member for a projection lens moved according to variation in copy magnification with the 2nd mirror mechanically. CONSTITUTION:A wire 30 between a pulley 42 and the fixation point 36 of the lens support member 7 for the wire 30 is extended straight in unmagnification copying operation, and a correcting member exerts no influence upon the wire 30. The lens support member 7 is moved to left in enlargement copying operation, and the wire 30 comes into slide contact with the projection curved surface 38a of the correcting member 39a according to the extent of movement. In this case, the contour of the projection curved surface 38a corresponds to the amount of optical path correction necessary for the enlargement copying operation, so the extent of movement of the 2nd mirror is specified according to the variation in copy magnification, correcting the optical path lenght properly. The lens support member is moved to right in reduction copying operation and a correction is made as well as in the enlargement copying operation. Thus, the optical path length is corrected accurately through the simple constitution.

Filed: 1984-05-08
Abstract: PURPOSE:To attain a device for retransmitting a retransmission signal having an optional delay time to an incoming signal without distortion by synchronizing an on/off timing with a switching timing of two input/output switches. CONSTITUTION:A gamma2 satisfying gamma1=n<gamma>+gamma2(0<=gamma2<gamma) is obtained, where gamma1[sec] is a desired delay time of the retransmission signal to an external incoming signal, and a switch 11 is switched from the input signal to a feedback signal after a time gamma+gamma2[sec] after the incoming pulse.

Title: Temperature controller for heat plant
Inventor: SASAKI TOMOZOU
IPC: F28F27/00
Filed: 1980-07-04
Abstract: PURPOSE: To prevent an overshooting of the temperature of a heat medium on a  load side at the start of the plant by a method wherein a heat medium on a heat  source side is flowed to a heat exchanger through a heat accumulator only at the  start of the plant operation.  
     CONSTITUTION: Prior to the start of the plant, the heat source 1 is driven to accumulate heat in the heat accumulator 8. At the start of the plant operation, turn- over valves 12 and 13 as well as a flow rate adjusting valve 6 are controlled by a turn-over control mechanism 15, so that the heat medium on the heat source side provided by the heat source 1 flows into the heat accumulator 8 and after receiving the heat supply flows into the heat exchanger 3. Within the heat exchanger 3, the heat exchange is carried out between the heat medium on the heat source and that on the load side. When the temperature of the heat medium on the load side reaches a target value, a temperature detector 14 sends a signal to the turn-over control mechanism 15 which controls the turn-over valves 12 and 13 and the flow rate adjusting valve 6. In this instance, the heat medium from the heat source 1 is flowed directly into the heat exchanger 3 without flowing through the heat accumulator 8.
